MacBook turns on after 10mn
Hi, I have an isssue with my macbook Air.
It never fell, never got anything spilled on it, it’s been taken care of with outmost care. I’ve been using it daily since 2015 and it never failed me.
- macOS Mojave
- Battery still running good
Now, it’s been a few months since I’ve been encountering this issue.
My macbook won’t turn on directly when I press the power button. I’ll hear the fan running but the screen remains black. Not pitch black as if the computer was completely shut down but black as in the computer is definitely getting some energy.
The weird thing is that if after I pressed the power button, I leave it, it’ll turn on finally after 8-10mn directly on the authentication screen (No loader bar). The same thing is if close the lid after using it a bit, after an hour or so (I guess when it goes on sleep) it won’t wake up. It’ll be shutdown.
What I tried :
- Reset of the PRAM/NVRAM
- Reset of SMC
- Change of battery
- Reset of the SSD and new install of OS.
- Opened it and cleaned the fan
When it’s finally turned on, I try multiple stuff like check of permissions and check of the SSD. Tried changing the parameters of the sleep pattern.
When it’s turned on, it works perfectly and if I shut it down and restart it right after, it also work perfectly.
I’m trying to look for solutions for now as if I take it to an Apple store, I’m sure they’ll charge me a lot for replacing the logic board or some other things and it’s not under warranty anymore so I’d rather buy a new one.
Thank you :)
